1 00:00:00,420 --> 00:00:08,310 It seemed initially successful now will just go ahead and try to export and hardware, including a bit 2 00:00:08,310 --> 00:00:12,380 steep, and they will proceed with launching LSD. 3 00:00:13,230 --> 00:00:21,900 So here we will start developing an application for our private time and the watchdog timer that we 4 00:00:21,900 --> 00:00:24,520 have to give private to the CPA. 5 00:00:25,090 --> 00:00:32,310 So now, since the best way to find out which are the drivers that should be utilized for a specific 6 00:00:32,330 --> 00:00:37,140 benefit, you just need to first create an application project already just go ahead. 7 00:00:37,140 --> 00:00:40,640 And first we will be working on end waste of time. 8 00:00:40,760 --> 00:00:43,610 Right click next and then select Hello. 9 00:00:43,620 --> 00:00:50,310 Now, the watchdog timer is useful, for example, as you have an application, so we always have an 10 00:00:50,310 --> 00:00:57,600 idea about what is the maximum time that our application could take to complete its entire operation. 11 00:00:57,830 --> 00:01:06,480 OK, so let's assume if we are stuck somewhere and then we exceed the time that our application should 12 00:01:06,480 --> 00:01:13,830 take in a normal, it is taking more time than the maximum time that we have computed for an application. 13 00:01:13,830 --> 00:01:23,310 And that is the easiest strategy is to restart our application so that this could bring out our application 14 00:01:23,310 --> 00:01:24,310 from a day, right? 15 00:01:24,330 --> 00:01:26,820 So that is where and most of them are useful. 16 00:01:26,820 --> 00:01:32,610 So it will keep a track of the time that our application is seeking. 17 00:01:32,910 --> 00:01:39,750 And if the application they secured within the specified limit, we will be restarting most of them 18 00:01:39,750 --> 00:01:40,350 right then. 19 00:01:40,770 --> 00:01:43,200 So in that case, it won't be visiting our system. 20 00:01:43,200 --> 00:01:49,790 But if the time consumed by our application is greater than the maximum specified limit in that year's 21 00:01:50,280 --> 00:01:55,890 time, we will need a reset signal and then that reset signal could be. 22 00:01:57,090 --> 00:02:01,020 Used to restart or bring back our application out of date. 23 00:02:01,170 --> 00:02:01,440 Right. 24 00:02:01,560 --> 00:02:06,660 In fact, we do have a function, so we have a specific function to check that there was the time where 25 00:02:06,660 --> 00:02:07,980 it expired or not. 26 00:02:08,010 --> 00:02:08,280 Right. 27 00:02:08,610 --> 00:02:12,600 So if that we didn't do that, basically meet our watchdog timer expired. 28 00:02:12,690 --> 00:02:13,620 Thank you. 29 00:02:13,680 --> 00:02:16,800 We will be understanding those things as we progress. 30 00:02:16,800 --> 00:02:20,100 But right now we have created a new application. 31 00:02:20,100 --> 00:02:26,880 Now you could see by default, you have a pseudonym A. You watchdog timer being enabled, right? 32 00:02:26,880 --> 00:02:33,450 And for that reason, you could see both of them are outdated and Mrs. White, and the driver for them 33 00:02:33,450 --> 00:02:37,060 is a pseudo bloody and sue time. 34 00:02:37,110 --> 00:02:37,470 All right. 35 00:02:38,070 --> 00:02:42,420 So we'll just be proceeding first with the washed-up payment, and then we'll proceed to the time where 36 00:02:42,420 --> 00:02:46,740 in fact, we're finding there are a lot of similarities between these two things. 37 00:02:47,670 --> 00:02:48,000 OK. 38 00:02:48,300 --> 00:02:52,950 So let me just go ahead, and the first thing that we do is to include the driver, right? 39 00:02:53,790 --> 00:02:56,010 So even though you would see it's you. 40 00:02:56,340 --> 00:02:59,250 But this doesn't exist in a snow control any. 41 00:02:59,510 --> 00:03:06,390 So this is how just the drivers that need to decide the independent block that we have within processing 42 00:03:06,390 --> 00:03:06,770 system. 43 00:03:07,050 --> 00:03:08,730 So let it just go ahead. 44 00:03:08,730 --> 00:03:15,650 And the next important we'll find which is experimenters, don't it? 45 00:03:15,680 --> 00:03:15,900 Right? 46 00:03:15,900 --> 00:03:18,060 So those are the two a device that we require. 47 00:03:18,100 --> 00:03:22,020 No, we'll just go ahead inside our washed up mode drivers. 48 00:03:22,470 --> 00:03:27,570 So some of the fundamentals, which are very, very useful, would just be going through them, right? 49 00:03:28,940 --> 00:03:29,810 So the. 50 00:03:30,960 --> 00:03:34,040 S x c u. 51 00:03:34,530 --> 00:03:40,320 Excess sea washed, optimal support following feature, so you have washed up mud, you have the timer 52 00:03:40,320 --> 00:03:42,800 mode and then you have a lot more. 53 00:03:43,020 --> 00:03:49,110 So what washed off more or less will be understanding in a washed up ward when the county reaches zero, 54 00:03:49,140 --> 00:03:58,680 the reset flag is sick, OK, in the risk stack is registered and the WD Reset request pin is asserted, 55 00:03:58,680 --> 00:04:00,120 granting the system reset right. 56 00:04:00,420 --> 00:04:08,930 So you would clearly see the reset flag is secondary six Typekit eight, causing a system reset rate. 57 00:04:09,920 --> 00:04:14,860 No, this research flag is not reset by normal process, be set down. 58 00:04:15,230 --> 00:04:18,150 We need to apply one to clear. 59 00:04:18,590 --> 00:04:21,500 This is the important thing to look now. 60 00:04:21,500 --> 00:04:26,870 This enable us to differentiate between normal risk and decent goals by watchdog time. 61 00:04:27,020 --> 00:04:36,440 Right now, use need to call a restart or stock them periodically to avoid resetting of system if watchdog 62 00:04:37,220 --> 00:04:41,660 reaches to the maximum crowd, that could, right? 63 00:04:42,880 --> 00:04:47,620 So now what we'll do is we'll understand some of the fundamental reality to Vostok, right? 64 00:04:47,980 --> 00:04:54,280 So the world of climate supports falling more, so we have a washed up mode, we have a timer mode and 65 00:04:54,280 --> 00:04:55,800 we have to reload, right? 66 00:04:56,110 --> 00:04:57,540 So what washed up movies? 67 00:04:57,550 --> 00:04:59,500 So we have certain foul rate. 68 00:04:59,770 --> 00:05:02,980 So we specified the Cold War and watched watchdog timer. 69 00:05:03,250 --> 00:05:03,680 OK. 70 00:05:03,700 --> 00:05:05,670 And it basically is a down count. 71 00:05:05,680 --> 00:05:08,940 And so whatever value is specified with start discriminating? 72 00:05:09,610 --> 00:05:10,660 OK with each clock. 73 00:05:11,260 --> 00:05:13,300 And we already know the lock. 74 00:05:13,300 --> 00:05:19,510 The gate, which are washed up timer will be operating, is half off the clock rate. 75 00:05:19,510 --> 00:05:24,280 So that is three three three megahertz now when Countdown reaches zero eight. 76 00:05:24,320 --> 00:05:28,690 So as soon as I count three two zero, the reset flag is sick, OK? 77 00:05:28,930 --> 00:05:32,100 In the three, this this right? 78 00:05:32,810 --> 00:05:36,080 And that basically God's system is right. 79 00:05:36,100 --> 00:05:38,170 This is an operation that we have in and washed up. 80 00:05:38,170 --> 00:05:42,340 More so will be simply specifying, OK, I'll start counting downward. 81 00:05:42,610 --> 00:05:50,080 And as soon as we reach is to zero, we will be resetting our system right and will also be setting 82 00:05:50,080 --> 00:05:50,670 the flag in. 83 00:05:50,790 --> 00:05:55,840 You 60 decided this right now this V60, this red. 84 00:05:55,840 --> 00:06:03,760 This flag cannot be decided by a normal processor is OK, and we need to clear it by writing a value 85 00:06:03,760 --> 00:06:04,450 of what right. 86 00:06:04,450 --> 00:06:11,110 And this help us to distinguish between whether the reset is caused by a watchdog timer timeout or whether 87 00:06:11,110 --> 00:06:13,090 it is caused by normal rate. 88 00:06:13,570 --> 00:06:20,050 So remember, if you do not want to reset your system, you need to periodically call it restart watchdog 89 00:06:20,050 --> 00:06:24,640 timer EPA OK, now before watchdog timer demonstrate. 90 00:06:25,450 --> 00:06:33,070 And then we also have an EPA is washed off expired to verify whether the washed up is the source of 91 00:06:33,070 --> 00:06:35,960 our last visit or whether it is normal. 92 00:06:36,380 --> 00:06:36,590 Right. 93 00:06:36,650 --> 00:06:44,470 So if the function returns true, right, and that is it basically been washed off is something which 94 00:06:44,470 --> 00:06:46,840 is causing the last systems, right? 95 00:06:47,860 --> 00:06:54,970 And application, they need to clear the risk, right, so this is the fundamental related to a washed 96 00:06:54,970 --> 00:06:55,120 up. 97 00:06:55,360 --> 00:06:59,170 Then second, when we have a timer rate again, we will be specifying the count. 98 00:06:59,530 --> 00:07:05,040 And then when we count the Regis to zero, the event flag is something that interrupts students register. 99 00:07:05,740 --> 00:07:11,860 And if interests are enabled, we have an interest pending in a queue with an idea of that, right? 100 00:07:11,860 --> 00:07:16,950 So this basically Genndy and intro as soon as the outer reaches to a zero rate. 101 00:07:16,960 --> 00:07:19,220 So this is what we refer to as it time. 102 00:07:19,480 --> 00:07:19,780 Right? 103 00:07:20,410 --> 00:07:21,610 So these are the two modes. 104 00:07:21,610 --> 00:07:24,810 As we probably saw, there will also be an ascending in order to reload. 105 00:07:25,270 --> 00:07:32,020 So these are some of the fundamental remembering that most of all, they need a reset signal for our 106 00:07:32,020 --> 00:07:35,350 system, whereas if we consider time a more to needs and interests. 107 00:07:35,350 --> 00:07:41,790 So as you progress further with an interest, we'll be understanding more on how we utilize it in a 108 00:07:41,800 --> 00:07:42,160 time. 109 00:07:42,640 --> 00:07:48,760 So we'll be majorly focusing in more sub mode as well as in auto reload mode here, right? 110 00:07:49,420 --> 00:07:55,990 Again, if you want to do driver, we have a two structure, set config structure and instant structure, 111 00:07:55,990 --> 00:07:59,980 so we'll just be declaring an instance of this to in our mean application. 112 00:08:00,130 --> 00:08:00,490 OK. 113 00:08:01,390 --> 00:08:05,830 So the instance structure will be keeping simple. 114 00:08:06,070 --> 00:08:11,210 And when we consider the config structure, we'll be considering it to be a pointer. 115 00:08:11,410 --> 00:08:16,840 So let me just go ahead and try to use what stock code, right? 116 00:08:17,890 --> 00:08:21,580 So we have an instance structure and we have a fixed structure now. 117 00:08:21,610 --> 00:08:27,910 We proceed with the function, which could be used to initialize a washed up name, right? 118 00:08:28,270 --> 00:08:33,160 So let me just go ahead and mean this function as washed in it. 119 00:08:34,510 --> 00:08:34,840 OK. 120 00:08:35,140 --> 00:08:40,180 And we already know an entire process, so we need to find out the lookup config function that is the 121 00:08:40,180 --> 00:08:43,630 first thing that we do where we need to spice the device. 122 00:08:44,000 --> 00:08:44,200 Right. 123 00:08:44,230 --> 00:08:46,180 So we do have a look at config function. 124 00:08:46,180 --> 00:08:54,160 So let's just go ahead and connect config structure that is to bloody conflict will be close to this, 125 00:08:54,400 --> 00:08:57,220 where we just need to buy a CE device 80. 126 00:08:57,220 --> 00:09:01,280 So we'll be finding our device add next parameter dot h file. 127 00:09:01,360 --> 00:09:03,680 OK, here we just need to look for it. 128 00:09:04,540 --> 00:09:10,020 And you could clearly see we have x s c you washed off, right? 129 00:09:10,030 --> 00:09:11,920 So we'll just be copying this device. 130 00:09:11,920 --> 00:09:14,390 Aldi will be adding it to work. 131 00:09:14,620 --> 00:09:14,920 Right. 132 00:09:14,940 --> 00:09:18,340 This is the first step that we do for an initialization. 133 00:09:18,340 --> 00:09:22,390 The next step is to call an CMG initialize, right? 134 00:09:23,790 --> 00:09:31,860 So let me just see it initially and to call it the result of CE of the initials, we'll just be declaring 135 00:09:31,860 --> 00:09:34,290 one integer variable stupid rate. 136 00:09:34,290 --> 00:09:35,780 Does that indicate the argument? 137 00:09:35,790 --> 00:09:43,110 First one is an instance structure, which is w d wtt and then we have a WTT config and finally the 138 00:09:43,110 --> 00:09:43,650 B side. 139 00:09:43,800 --> 00:09:50,270 So W d d config, then this operator and then we have obesity rate this completely adequate. 140 00:09:50,430 --> 00:09:55,860 Now we just need to add a logic to A5, whether it is equals to excess success rate. 141 00:09:57,350 --> 00:10:02,120 So here will just be very frank with you, does is with specificity sets, is it that is the case. 142 00:10:02,120 --> 00:10:08,810 We'll just be mentioning WTT in Texas will else we will just be mentioning that b d in it. 143 00:10:09,290 --> 00:10:09,590 Right. 144 00:10:09,890 --> 00:10:15,110 Whenever you are utilizing an intermediate benefited or a complex paper, the good idea will always 145 00:10:15,110 --> 00:10:22,010 be to perform a self-test so that we will be making sure that hardware is configured correctly. 146 00:10:22,190 --> 00:10:29,000 So once you make your initialization successful, try to use this, this variable and call the self-test. 147 00:10:29,000 --> 00:10:34,490 So we do find the self-test available for most of the intermediate and complex paper, right? 148 00:10:34,520 --> 00:10:38,270 Again, this also readiness that you do similar to our CFD initially. 149 00:10:38,270 --> 00:10:44,980 So this very well could be also utilized with this case right now when we consider this or if it retains 150 00:10:45,000 --> 00:10:46,160 existing Texas. 151 00:10:46,160 --> 00:10:49,100 So that basically means that this is successful, right? 152 00:10:50,150 --> 00:10:52,370 So let's just call a self-test. 153 00:10:52,940 --> 00:10:59,690 OK, just after we verify the device initialization is successful, they'll just be updating the value 154 00:10:59,690 --> 00:11:06,210 of status to be equals to so saying here we just need to pass the instance, such as we just WD. 155 00:11:06,410 --> 00:11:11,950 And again, we will be performing the same comparison rate. 156 00:11:11,960 --> 00:11:15,550 But here now, if it is equal to success. 157 00:11:15,560 --> 00:11:19,460 So self test is successful, OK? 158 00:11:19,460 --> 00:11:24,650 And we could just mention the self test fee, right? 159 00:11:24,920 --> 00:11:30,290 So this you should be performing when you are looking around with n complex or an intermediate, they 160 00:11:30,290 --> 00:11:30,980 use it right? 161 00:11:31,430 --> 00:11:36,200 So let me just go ahead and call this an emotion in a mean program, right? 162 00:11:36,200 --> 00:11:42,080 So we'll just be deleting this spring and we'll be calling WD any do it over here, right? 163 00:11:42,170 --> 00:11:44,390 And once you do this, this complete step with. 164 00:11:45,420 --> 00:11:47,950 That is performing an initialization of op ed. 165 00:11:48,280 --> 00:11:52,110 Now the good idea would be to A580 that op ed if it is working correctly. 166 00:11:52,140 --> 00:11:52,410 Right? 167 00:11:52,920 --> 00:11:55,770 So we'll go ahead and rule out my ridiculous. 168 00:11:58,070 --> 00:12:04,970 We go back when it's to get a minute, will connect to account for and then we'll try to execute our 169 00:12:04,970 --> 00:12:05,570 application. 170 00:12:05,920 --> 00:12:08,900 Right click runners launch on hardball. 171 00:12:09,530 --> 00:12:15,590 No, I read your notes to verify whether self defense and initialization boot is set, but that's at 172 00:12:15,590 --> 00:12:22,640 this rate, and you could verify that WD and it is successful as well as celltex is also a success rate, 173 00:12:22,640 --> 00:12:24,380 so this complete a step. 174 00:12:24,380 --> 00:12:28,280 It now will proceed for writing an application rate. 175 00:12:28,290 --> 00:12:36,060 So this will give you an idea about how you use different EPAs which are available that private WD.
